RAILWAY-CROSSING.

Specification of Letters Patent.

Patented March 30, 1909.

Application led September 11, 1908. Serial No. 452,670.

T o all whom it may concern:

Be it known that I, POWELL O. ADAMS, a citizen of the United States, residing at Cameron, county of Milam, and State of Texas, have invented certain new and useful Improvements in Railway Crossings, of which the following is a specification.

My invention relates to crossings for railway tracks and particularly to means for closing the cut in the rails made for the Hanges of the wheels, and the object is to provide sliding members which can be easily operated to close the slot or cut in the crossing rails for the anges of the wheels so that a continuous tread will be formed for every wheel that passes over the crossing and to provide rigid mechanism for the tracks to 'prevent yielding of the track members.

The principal advantage of the crossing is to prevent the pounding of the wheels of trains against the track members.

Other objects and advantages will be fully explained in the following description and the invention will be more particularly pointed out in the claims.

Reference is had to the accompanying drawings which form a part of this application and specification.

Figure 1 is a plan view of the crossing. Fig. 2 is a horizontal section of the cylinders used for moving the movable rail sections. Fig. 3 is a detail View, being a sectional view of a rail section and its cooperating movable member. Fig. 4: is a detail plan view of the plate or slab for holding the movable member in place, or rather to prevent displacement of the movable member. Fig. 5 is an end view of a girder, showing the manner of supporting a tie'therein. Fig. 6 is a side elevation of a hanger for making the rail-joint rigid at each corner of the railway crossing. Fig. 7 is a detail view of a hanger for mounting the air-cylinder on the cross-ties. Fig. 8 is a side elevation of the cylinder, showing the manner of hanging the air-cylinder to the ties. Fig. 9 is a broken plan view of the girders about one corner of the crossing. Fig. 10 isa plan view of one rail section and its cooperating movable member, showing manner of operating the same by pneumatic pressure. Figs. 11 and 12 are detail views of the spike holder.

Similar characters of reference are used to indicate the same parts throughout the several views.

The meeting rails 1 and 2 at the crossing are preferably made integral and the rail sections 3, 1, 5, and 6 are rigid and may be made secure in any suitable manner. Means are provided for closing the space between the ends of the sections 3, t, 5, and 6 when a train is passing over the crossing. For this purpose movable members 7, 8, 9, and 10 are provided and means for moving the movable members are provided. Tracks 11 are provided for the movable members. Grooves 12 are cut in the sides of the movable members and slabs 13 are placed in the grooves 12 and secured to the rail sections 3, t, 5, and 6 by means of plates 14 and bolts l5. The movable members 7, 8, 9, and 10 are thus held against displacement as they can move only in line with their coperating rail sections. The movement of thf'e members 7, 8, 9, and 10 is approximately two inches, but they can be moved as great distance as desirable. The rail sections 3, 4, 5, and 6 may be mounted on plates 16 which are secured to cross ties 17 and corner ties 18. The ties are supported on girders 19 which are supported on piles 20 and on girders 21 which are supported on piles 22. The girders 21 extend from piles 20 on one side to the piles 2O on the other side and are supported on the piles 20 as well as on piles 22. Short girders 23 on the outside of girders 21 are supported on piles 20 and 22. The shape of the girders in cross-section is seen in corner. Cross ties 25 are supported on piles 2li and piles 20. Short cross ties 26 run longitudinally on girders 23 and 21 and are supported thereon, as shown in Fig. 9.

The meeting rail members 1 and 2 may be jointed to the rails ot' the line in the manner shown in Figs. 1 and 6. A bar of iron 27 is placed under the ties 17 which are adjacent to the rail joints and the bar is extended over and attached or bolted to the ties 25 and 2S and the ties 2S may rest on piles 29. This would make the joints rigid.

The movable members 7, S, 9, and 10 for one track are all moved simultaneously and pneumatic power is preferably used for moving these members. Cylinders and 31 are placed between two ties 17 below the rail sections 3, et, 5, and 6. The cylinders are hung on the ties 17 by means of plates 32 and hangers 33. The cylinders are provided with pistons 34 and piston rods 35. The movable members have downwardly projecting yokes 36 and the piston rods may be connected pivotally to the yokes 36. Air or steam may be admitted tothe cylinders 8O and 3l through ports 37 for driving the pistons and piston rods. The tracks stand normally open and the pneumatic pressure Vis used 4to .close the tracks Afor the passage -of trains. Springs 38 are yused to restore the movable members to normal positions. The springs 88 are mounted in barrels 39 and attached to the piston rods. The springs seat against thevbottom of the barrels 39.

The spikes et() which hold'the'bars :2T and which hold the rails on theties maybe held in 'placeby spike holders All. The tieis cut away at 42 so that the spike'holder Ll1 can `engage-the spike under the tie. The spike holder is preferably made Vof spring metal and'bent so that the ends will open to receive the spike. The upper part of the spike holder rests ontop of the spike.

`Having fully .described my invention, what l claim as new and desire to secure by `Letters Patent, is,-

l. railway crossing comprising meeting rail members rigid with each other at each corner crossing', continuous track forming members between said meeting rail members consisting of stationary rail members and movable rail members, tracks for said mov- Vable members adjacent tothe bases of said stationary members, said movable members having grooves in the undersides to receive said tracks, and plates bolted to said stationary members preventing displacement of said'movable members.

2. A railway crossing' having meeting rail members rigid with each other at each corner of the crossing, continuous .track forming members between said meeting rail members consisting' of `stationary rail members and movable rail members cooperating with said stationary members,`tracks for said movable members adjacent to the'bases of said stationary members, said movable members having grooves in the undersides thereof to receive said tracks and having grooves in the sides thereof, and plates in said side grooves bolted to said stationary members to'prevent displacement of said movable'members.

3. A railway crossing' comprising a `substructure consisting of piles, supporting girders resting on said piles, and cross ties supported on said girders; plates mounted oir-said ties, meeting rail members supported on said plates, continuous track forming -members consisting of stationary members .grooves to prevent the displacement of said movable -members et. A. railway crossing having' meeting' rail members rigid with each other at each corner of the crossing, continuous track forming membersbetween said. meeting rail members consisting of stationary rail members and movable rail members cooperating with said stationary rail members, and means for moving' said movable members consisting'of 75 yokes carried'by said movable members and projecting downwardly, pneumatic cylinders below said rail members, and pistons in said cylinders provided withrpiston rods operatively connected to said yokes.

5. A railway crossing having meeting rail members rigid with each other at each corner of the crossing, continuous track forming members between said meeting railmembers consisting of stationary rail members and movable rail members cooperating with said stationary members, and means for moving said movable members consisting of yokes carried by said movable members, pneumatic cylinders below said movable members, means for suspending said cylinders `fromthe ties, pistons in saidcylinders provided with piston rods operatively connectedwith saidyokes, land springs attached tosaid pistonrods and provided'with seats 95 Y whereby said springs restore said movable members to normal positions.

in testimony whereof, I set my hand in the presence 'of two witnesses, :this -Sth day of August, 1908.
